Analyses for Coupled Stress Field, Strain Field and Temperature Field of Adjacent Rock of Deep Mine Tunnel

Abstract：The stress-strain relation under the coupled condition was created, then the stress and strain were calculated in the different variable temperature range condition.The illustration showed that the shear stress, circumference displacement and the radius of the break zone and the plastic zone were larger under the coupled condition, and the methods to improve stabilization of adjacent rock were given under the coupled condition.
